To all whom it may concern Be it known that I, Bonner ESNAULT- Pnil'rnmn, a citizen of the Republic of France, residing in Billancourt, Seine, France, have invented certain new and use ful improvements in devices for heating the carburetors for combustion engines and more particularly for flying-machine engines, of which the following is a specified tion.

As it is well known the carburetors have to be heated to insure their proper operation in winter tune or when they are exposed to air drafts in order to prevent the freezing which first results from the low temperature of the air drawn in and then from decrease of the temperature caused by decreased pres-- sure produced by the suction itself. The

carburetors used in connection with flying machines being entirely exposed to air drafts created by the forward motion of the aeroplane must be specially protected and heated and it is for this purpose that the present device has been invented An important feature of the present system co'nsists in using hot oil contained in the crank-case of the engine, which is used for lubricating the shaft, the connecting rods and the cylinders and in which the crank studs and the heads of the connecting rods are dabbling for the purpose of heating the carburetor.

The invention may be carried out in different ways Obviously the most simple is to locate the part of the carbureters to be:

heated in the lower portion of the engine crank-case containing the oil, which to this end would have to be properly lowered and so arranged that all the parts would be bathed in the hot oil. Another way consists in drawing hot oil from the crank-case by reference to the annexed drawings in which FJ/TUI'BS- 1 and 2 are a vertical section on the line A;-A in. 2 and a plan view respectively or the carburetor located in the lower portion of the crank-case of a multicylindrical engine of the applicants type Fist. 3 shows the system carried out by means of an oil-circulation.

As shown in Fig. 1 the spraying nozzle of the carburetor a to which is connected a horizontal supply pipe a leading to the fuel. reservoir provided with a lion. and passing through the wall of the crank-case is located within the lower portion oi? the crankcase and is completely surrounded with oil. The nozzle a opens into an air.

therewith passes out of the crankcase and is provided with a valve it, outside tie crank-case, which, controls the gas i let. All these parts are, as it is well seen, entirely surrounded with hot lubricating oil.

Thence the pipe 9 passes, through various branches, to the valve boxes or the engine be supplied.

In the heating system of Fig. 3, the is taken from the crank-case A by means a small gear circulation pump Z which ior the oil through a pipe it into the jacket surrounding the additional air channel. at o the carburetor as well as the sup channel. and the spraying nestle a. Th jacket j is suitably partitioned, as at o, i order to insure the oil circulation about the walls to be heated, and the oil passes out of the jacket j -and returns to the crank-case through the pipe '5 connected therewith.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed what I claim as new and novel is:

1. In a gas engine, the combination of means for supplying gas to the engine and means for containing hot oil from the engine, said oil container being in hea transmitting relation. with said gas supplying means through a wall of said gassupplying means and adapted to heat said. gsswupplf; ing means by the hot oil therein. V

in agasfengine, the combination with a carbu'retpr, and means for containing hot oil iron the engine, said oil container being ini V-biiretcr through a Will of said carbureter and adapbed'tc heat said carbureter by the hot oil therein.

3. In a gas engine, the combination of a transmitting relation through-a Wall thereof with said crank casing and adapted to be heated by the oil in said casing.

A. In a gas engine, the combination of a crank casing containing lubricating oil, and a carburetor, suction and air-inlet pipes in heat transmitting relation through wslis thereof with said crank casing and adapted to be heated by the oil in said'casing.

5. Inc gas engine, the combination cf a crank casing containing lubricating oil, and

a curbureter located in the crank casing and adapted to be bathed in the oil, whereby the carbureter isheated by the oil contained in 0 In witness whereof I have hereunto signed any name this 27 day of September 1910, in

the-presence of two subscribing Witnesses.
